hash.each do |key, array| puts “#{key}—–” puts array end Regarding order I should add, that in 1.8 the items will be iterated in random order (well, actually in an order defined by Fixnum’s hashing function), while in 1.9 it will be iterated in the order of the literal.
Whether the browser asks the user or not is down to the preferences in the browser. You can’t bypass those preference, otherwise it would violate user’s security. What you can do is make sure you’re sending the browser as much information as possible to help it make for a good user experience. If you’re not … Read more
If you are under some Unix terminal (xterm, gnome-terminal …), you can use console codes: #include <stdio.h> #define clear() printf(“\033[H\033[J”) #define gotoxy(x,y) printf(“\033[%d;%dH”, (y), (x)) int main(void) { int number; clear(); printf( “Enter your number in the box below\n” “+—————–+\n” “| |\n” “+—————–+\n” ); gotoxy(2, 3); scanf(“%d”, &number); return 0; } Or using Box-drawing characters: … Read more
When you specify a JSON list as CMD in a Dockerfile, it will not be executed in a shell, so the usual shell functions, like stdout and stderr redirection, won’t work. From the documentation: The exec form is parsed as a JSON array, which means that you must use double-quotes (“) around words not single-quotes … Read more
Linebreaks in HTML are represented by <br /> element, not by the \n character. Even more, open the average HTML source code by rightclick, View Source in browser and you’ll “see” \n over all place. They are however not presented as such in the final HTML presentation. Only the <br /> will. So, yes, you … Read more
You could convert it to a string instead of printing the list directly: print(“, “.join(LIST)) If the elements in the list aren’t strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don’t), like so: LIST = [1, “foo”, 3.5, { “hello”: “bye” }] print( … Read more
The syntax you are trying to use is non-standard, it works only in some compilers and I discourage using it. Also, forget the FORMAT() statements for good, they are obsolete. You can get your own number inside the format string when you construct it yourself from several parts character(80) :: form form = ‘( (i10,1x))’ … Read more
It sounds like you want an out of source build. There are a couple of ways you can create an out of source build. Do what you were doing, run cd /path/to/my/build/folder cmake /path/to/my/source/folder which will cause cmake to generate a build tree in /path/to/my/build/folder for the source tree in /path/to/my/source/folder. Once you’ve created it, … Read more
If your program is linked with /SUBSYSTEM:WINDOWS you will not see the console output unless you allocate a console. Here is code for the allocate console option. With this method you should not need to change your linker settings or create a WinMain. static void OpenConsole() { int outHandle, errHandle, inHandle; FILE *outFile, *errFile, *inFile; … Read more
With static (lexical) scoping, the structure of the program source code determines what variables you are referring to. With dynamic scoping, the runtime state of the program stack determines what variable you are referring to. This is likely a very unfamiliar concept, since basically every programming language in wide use today (except perhaps emacs lisp) … Read more
